Electricity price on the way down

Wholesale electricity prices have reduced in recent months however many end users are not seeing the benefits. It is expected the reduction in wholesale electricity prices will not flow onto household and businesses bills until 2024.

Federal treasury has analysed the wholesale electricity market in November 2022 and compared it with the prices we saw in December. Analysis showed wholesale prices dropped but Edge has previously shown renewable energy has not significantly increased, gas supply has not changed, thermal generation has remained unchanged so why the drop in the cost of electricity?

In late December the Federal government stepped into the energy market and intervened, essentially disconnecting the domestic energy market from the international energy market. This intervention put caps on the domestic price of wholesale gas and the price of coal.

Following these caps being put in place the domestic electricity market corrected, and both spot and futures contracts dropped to match an underlying cost of production for electricity based on these new capped fuel prices.

While the wholesale market dropped almost overnight it will take time for the lower costs to flow through to end users unless their load is spot exposed in Q123. Retailers had already locked in the majority of pricing for end users prior to the market dropping due to the intervention, so most end user electricity bills will reflect the historic high wholesale prices.

The federal analysis claims the price caps on coal and gas have dropped prices in QLD by 44% and 38% in NSW. Does this mean electricity bills are going to drop a similar amount? Well, the bad news is no. Retail bills are normally locked in well in advance so many large users have locked in pricing for 2023. The underlying energy costs are only part of the retail bill as other costs include transmission, distribution and AEMO charges which unfortunately have not decreased and have the potential to increase as the market evolves.

While the market intervention was a necessary step to insulate end users from the escalating international energy prices due to the war in Ukraine, the next step is to continue to drive down prices as the country transitions to renewables. We must keep in mind the transition to renewables will come at a cost. Renewable energy requires more transmission lines to connect the generators to the grid, they require specialised services to maintain the security of the grid and will also require a higher cost generation or storage to provide firming for around the clock supply.

While the underlying cost of electricity will drop with more renewable energy entering the market, the other costs on the electricity bill will now represent a higher proportion and are likely to increase.

Market Report – Quarter 3 2022

Overview of National Electricity Market (NEM) Quarter 3 2022

International drivers continue to increase gas and electricity prices across the NEM. The main reason for this increase has been and continues to be the tight supply / demand balance resulting from Gas flow restriction in Europe, associated with the war in Ukraine. The reduced flow of gas in Europe has resulted in a greater demand for Australian gas that in turn has put cost pressures on Australian gas market. Higher priced gas then links into to Australian electricity market, leading to higher spot and futures electricity prices.

For Q322 electricity spot prices averaged $216/MWh across the (NEM). The Q322 average spot price of electricity was close to matching the all time record of $264/MWh that occurred in Q222. Interestingly, the average price of electricity for Q322 was more than three times higher than the same quarter the previous year. In Q321the average price of electricity was $58/MWh.

NEM operational demand increased by 2.6% or 559MW to 22,414 MW compared with the same quarter last year. We also saw demand increase for the first time in Q3 since 2015. Households and businesses used more electricity from the grid as a result of their underlying electricity consumption increasing and the output from their rooftop Photovoltaic systems (PV) not generating as much as normal due to cloudy conditions.

High spot prices occurred at the start of Q322 on the back of record high spot prices seen across Q222. The July NEM monthly average of $360/MWh was $23/MWh higher than the June 2022 average of $337/MWh. Later on in the quarter spot prices fell with August Electricity prices averaging $145/MWh across the NEM. Until this year QLD, NSW, VIC and TAS have not recorded a Q3 average electricity price of over $100/MWh. South Australia reached this milestone in Q316 at $119/MWh.

Historically Q3 is not a volatile quarter, but this year it is different, Q322 saw 24% of the dispatch intervals with a price over $300/MWh. This is on the back of the previous quarter, in July prices exceeded $300/MWh 61% of the time, the highest monthly proportion since  the start of NEM. Many intervals saw prices in the $300-$500/MWh range resulting in spot prices moving above the historical price cap threshold of $300/MWh.

Below are the drivers that elevated spot prices and volatility in Q322.

  • A reliance on thermal generation (coal and gas fired) with higher fuel cost due to the increased demand for these resources internationally.
  • Hydro generation setting prices at elevated levels due to limited water supply and bids adjusted to meet revised trading strategies.
  • An increase in demand as consumption increased and rooftop PV generation reduced due to cloudy skies.
  • Price volatility significantly increased the average spot price of electricity with large jumps in spot price due to the distribution of generation offers within the bid stack. The market operator stacks all offers from lowest to highest to build the bid stack. The spot price for a trading interval is the offer price of the marginal unit at the required generation level to meet demand. The bid stack ranges from -$1,000 to $15,500/MWh. During August the spot price reached over $1,000/MWh as generators withdrew generation for technical and economic reasons.
  • With higher average electricity prices we also saw less negative electricity prices across the NEM. In the previous year we experienced negative prices 17% of the time but for Q3 we have only experienced negative prices 9% of the time.

Weather

A La Niña event was declared across the NEM increasing the likelihood of above average winter-spring rainfall across much of northern and eastern Australia, while a negative Indian Ocean Dipole (IOD) event increased the likelihood of rainfall across southern and eastern Australia. Q322 was very wet, with many sites recording their wettest July on record. Wet weather continued across Q3 with September’s rainfall being the fifth highest on record across Australia. Temperatures at the beginning of the quarter were below average in many parts of Victoria and Tasmania and above average minimum temperatures occurred across south-east Australia.

La Niña resulted in wet and cloudy conditions impacting solar generation and the supply of coal to power stations, in additon to the export market resulting in higher prices.

Electricity Demand

As outlined above the NEM demand has changed since the same time last year, the below chart shows this graphically.

NEM Spot Prices

NEM spot prices have increased significantly and have reached unprecedented levels.

The cost of the underlying fuels for generators has led to these increases. Coal and gas prices are at all time highs due to international demands leading to a high cost of generation. The chart shows the correlation between East coast gas price and the price of electricity. Coal also corelated closely to the cost of generation and a resulting electricity spot price.

Prices have also increased as renewables generation (solar, wind and hydro) is lower due to cloud cover reducing solar, low storage levels reducing hydro generation and hence it bids in at higher prices. There have also been large swings in the output from wind which results in spot market volatility.

 

Generation and Offer Prices

Gas contributed the most to supply in Q322 and as result of the high cost of gas this has influenced the average spot price.The lower volume of generation from coal was a result of bidding behaviour withdrawing thermal capacity and intermittent generation like solar and wind taking a larger market share.

A lower capacity factor for coal generation has resulted in coal fired availability moving higher up the bid stack resulting in coal fired generation needing to dispatch at higher spot prices to meet their long run average costs.

 

 

 

 

 

 

 

 

 

 

 

Emissions

NEM emissions intensities declined this quarter slightly to 0.6 tCO2-e/MWh. Total emissions were 0.2% lower than Q321.

Australian Stock Exchange (ASX)

The futures market was influenced by a higher spot market, gas prices and the delays experienced with large scale renewables, a slowing in the rooftop PV market and climate conditions likely to reduce the output from solar generation.

The future price of electricity traded on the ASX for Calendar 2023 (Cal 23) continued to increase in price across the quarter in the four NEM mainland regions. Cal 23 New South Wales futures finished the quarter at $232/MWh, with Queensland at $224/MWh, South Australia at $193/MWh and Victoria at $157/MWh.

Winter is coming

Now I am a major Game of Thrones fan, but I never thought moving to Australia that I would turn into Ned Stark and constantly worry about a Northern Hemisphere Winter. But, as we are hurtling towards those cooler months in t’north and following the tumultuous Q2 and start of Q3 in the NEM, I am preaching that the Northern ‘Winter is Coming’ and even down here in Australia we must be ready.

As background Northern Europe, UK, France, Belgium, Germany etc., rely on feeds of Gas from Norway and Russia. Gas is significant in Europe as a 1-degree shift in temperature can result in around 5% of domestic demand increase, or decrease, due to most homes being heated via Gas-Central heating. With a third La Niña about to be called in the Southern hemisphere and La Niña, correlated with colder winters in Europe, with increased snowfall, as it shifts the jet stream north to the pole and increases storms across Northern Europe, this can only mean an increase this heating demand.

This confluence of events would usually increase my concern for a tight supply in the European market, but this year is different. Ignoring for now the Russian flows, we will circle back to that later, Norway’s Energy Minister has already raised the possibility that they may restrict electricity exports with possible restrictions to Gas flows as well. With much of their electricity coming from hydro, and after an un-seasonably warm summer period, Norway has stated the priority will be to refill the reservoirs over winter, rather than secure the energy supply of their European neighbours. With this flow being restricted into Northern Europe, coupled with a diminishing fleet of coal and nuclear options, gas will be the favoured source of domestic supply for Northern Europe. Although there are other interconnectors, it is anticipated these will either be significantly under utilised or such a price differential within a domestic market will occur to ensure flows to a single market will ensue. This could be facilitated by pushing those areas (countries) price up to exorbitant amounts to ensure flow across the interconnector and shore up domestic supply. With flows of course favouring higher priced regions.

Now let’s put Russia into the mix. Russia announced this week that the Nord-Stream 1 pipeline, a crucial pipeline for gas flow into Europe, required maintenance from the 31st August. This happens to coincide with European markets trying to firm up winter supply by filling storage and Russia increasing aggression to the Ukraine, but I am sure that was a coincidence.

The 3-day maintenance will have a return to service for the 2nd September. But how likely is this to return? Well, if the last outage is anything to go by, where only 40% of the required flow reached Europe and the delivery of the required turbine was strangely delayed, the price increase was significant and totally in Russian control. Now with this latest outage and flows expected to be around 5% of the obligations agreed with the EU, the cynic in me wondered if Putin is trying to offset the sanctions place on Russia by pushing the cost of Gas to exorbitant amounts. If he can sell his 5% for the same as the revenue from the already inflated 40% and free the remaining gas for sale to more amiable neighbours, he is in a win-win situation.

The real fear is that this flow remains low for the whole of Europe’s winter, which would not only put massive strain on the cost of generation but also lead to many retailers simply not able to meet their obligations and go under. There is also a risk of lack of supply and therefore blackouts as well as increasing costs on an already strained economic environment.

To mitigate this, European generators are throwing out their climate targets with the baby and the bath water in favour of supply and are scrambling to shore up gas supply and return coal-fired power stations from cold storage. The Mehrun Coal-Fired Power plant in Saxony Germany came back online at the start of August, Uniper have just announced they are re-commissioning the Heyden plant in North Rhine-Westphalia and in the UK, the government has made moves to re-open the rough gas storage facility, 25% of it initially, ignoring the safety concerns which led to its original closure. But this will not be enough, and this is where Australia needs to brace itself for a secondary wave of impacts.

LNG and coal exports into Europe will increase, as the price differential will be significant. The ensuing impact through the JKM on the domestic gas market, and coal export price will affect the replenishment of the longer-term running costs of our own generators.

Although significant volume should be pre-hedged, these prices will start feeding through, nothing is stopping the trading opportunity cost being passed through by generators. They will argue the replenishment of the stockpile will need to factor these spot and forwards prices, interesting that doesn’t flow through in a bear’s market though.  What does that mean for our summer, well it means the high prices aren’t going anywhere fast. The shortage of supply in the NEM may be diminished, with most, if not all units now returned from overhaul, yet the price is continuing to take advantage of, and reflect the international fundamentals rather than the real long run average cost of the asset.

With the Capacity Mechanism being put on ice and strengthening Safeguard Mechanisms already announced by the Labor Government, coupled with favourable international fundamental conditions providing political cover for generators, could this be the last hurrah for coal and gas generators to eek the last value from these assets?

Either way be under no illusions, with the Northern winter hurtling towards us, European prices already building in shortfalls in supply and no end to the Ukraine conflict in sight, the Vega sensitivity is going off the chart and is not going to be subsiding anytime soon. As such Australia, and especially its energy markets need to brace, for the fallout.

To circle back to Game of Thrones, Ramsay Bolton stated, “If you think this has a happy ending, you haven’t been paying attention” for ‘winter is coming’ and we must be prepared.

Is UFE the UIG of Australia?

Anyone who knew me in my past life in the UK knows that I harped on about Unidentified Gas (UIG) A LOT!

The idea behind UIG is simple, allocate the gas which couldn’t be attributed to a meter in an area across all end users in that area, in which it was used (off-taken). Seems simple right. But when was the last time you actually gave a meter reading? Possibly six months to a year ago? Well that means your off-take (unless you are on a smart meter) is estimated and you will be either over or under on allocated unidentified gas.

Although this seems sensible with everyone eventually giving a meter read and therefore it will all work out in the wash, what exacerbates the issue, especially at the moment, is the extreme increase in the gas price at which these charges are now passed through to retailers and then in turn our bills.

Now what does understating this UK gas usage or allocation have to do with Australia? Well, quite a lot. The system is similar, but not the same.

Following Global Settlements being introduced by AEMO we have started seeing Australia’s version of these charges coming into our bills. We allocate the unidentified – called Unaccounted for Energy (UFE) within each region by the off-takers in that area.

What we are not doing yet, which in the UK’s defense they do there (through XOServe), is take into account those meters which are half hourly ready (smart(er) meters) and therefore their usage should be known. Currently in Australia the offtake in a region will be directly linked to your proportion of an energy being allocated to you and you literally have no say in these charges, despite having updated metering capability.

The sore point of it all is that this is occurring at a time when our electricity market is extremely high and therefore there is a possibility of the combination of large UFEs  being passed through to end users at high prices, with companies having no control over the volume or price it is passed through at. This is leading to significant shocks to companies’ outgoings, as there is little to no visibility on the charge on any given month, and no way to forecast them to budget.

I fear that UFE will become my new soap box issue, and I can guarantee this isn’t the last anyone will hear on this. I am pretty sure I won’t be the only one who will be making noise.

Labor pushes ahead with a controversial capacity market

What is the goal of a capacity electricity market?

You may be forgiven for not sitting through the full press conference last Thursday, where the Albanese government stated Australia would be strengthening their 2030 targets to 43% under the Paris Agreement. However, if you had, around 30 minutes in you would have heard Chris Bowen, the newly appointed Minister for Climate Change and Energy state, “in relation to the short term, State and Territory Ministers agreed with me last week, that we should proceed at haste, at pace, with the capacity mechanism. I asked, on behalf of all Energy Ministers, the Energy Security Board to proceed with that work, at speed, and they are doing that. I am very confident I will be able to get agreement of State and Territory Ministers for a comprehensive capacity mechanism and I’ll have more to say when that work is ready.”

Well that work dropped this morning (20th June) at 7am. They have given those who wish to respond until (25th July) to submit their views on this paper so at pace it shall be. However; given the response following the ESB Post 2025 paper I am not sure that any amount of noise and lobbying from the industry is going to stop this juggernaut from achieving its goal, especially since it is being backed by those generators who have the most to gain from this market. Not only that, but unless there is a big bump in the road, a first look Capacity Mechanism will be in place by 1st July 2025.

What is the goal of this market? – Well in my opinion there is only one reason that this would be encouraged and that is to subsidise coal-fired power stations which have had their financial viability severely questioned by the growing penetration of lower cost renewables within the system. Don’t get me wrong, the longer-term markets have the potential to encourage other faster starting generators onto the market, but this hasn’t really been the case in other capacity markets i.e. Great Britain (GB).

This argument is only further strengthened when looking at how the GB Market ended up achieving their stability, in their high renewable penetrated market, which is from nuclear power which has been guaranteed a strike price of £92.50/MWH or ~$163/MWh. Thus, making any capacity market payment minuscule in comparison to the underpinning of the generation at that rate.

The ESB are arguing, and convincing themselves and the government in the process, that this mechanism is the answer to AEMO’s ISP step change scenario, in which demand increases and coal exits the system. If that is indeed their argument, then they are ultimately stating they cannot efficiently run a system in which coal is not part of the generation mix and unless this is financially managed there will be a ‘disorderly transition.’

The question therefore isn’t will there be a capacity mechanism from July 25, but how centralised or decentralised will the final design be? Will it sit as a Physical Retailer Reliability Obligation – PRRO design, one in which the market determines for itself the level of the required capacity, or do we go wholly down the regulated route with AEMO determining in long term auctions (similar to the GB model which has several T-year auctions) and they forecast demand and supply to determine the required level of capacity and sell these capacity certificates to retailers to meet their requirements.

There is no grey area for the ESB, they have stated openly in the paper they wish for the forecasting and determination of the capacity requirements to be centralised and for AEMO to manage these purchases on behalf of market participants. In essence they would moderate the capacity of these generators, for a cost, at certain times of day or periods of high system stress to allow them to ensure capacity is available to the market operator when needed. End users would then pay for that management of the system and their portion of that capacity.

The other point to note, keenly hidden within the paper is the four yearly review of the Reliability Standard and Settings Review (RSSR) that is about to be undertaken, with significant interest been taken in the Market Cap, especially given the gas price cap is equating to a marginal cost of generation higher than the electricity price cap (Presuming a normal heat rate of 8-12). If the caps are risen for both the caps $300/MWh and spot $15,100/MWh markets as expected, could the requirement of ‘capacity’ in the market become a moot point? Surely the exacerbation of the current situation could be avoided if the gas generators were certain of meeting the cost of generation and you cannot truly believe that a market cannot efficiently run with enough capacity if they are achieving $15,100/MWh or possibly more?

The real key argument which has not been addressed by the paper however, is the idea that aging coal plants are unlikely to be able to ramp in time to fill the gaps between this growing renewable penetration. Therefore, the question really needs to be asked is this the right investment if you really want to transition this grid or should this be put into different technology rather than prolonging the life of unsuitable assets?

Ultimately however the bottom line remains ‘user pays.’ As such any one of the options being floated will be passed through to end users through retailer or network tariffs.

I will let the retailers and generators pick apart the nuances of the paper, but needless to say the government will be pushing ahead with this in some form, the only question will be how much say we will have in the centralisation of the market or not, and therefore how much control retailers will have on the costs of this capacity.

AEMO Suspends the Market

Below is the media release from AEMO after it suspended the National Electricity market at 14:05 today.

AEMO today announced that it has suspended the spot market in all regions of the National Electricity Market (NEM) from 14:05 AEST, under the National Electricity Rules (NER).

AEMO has taken this step because it has become impossible to continue operating the spot market while ensuring a secure and reliable supply of electricity for consumers in accordance with the NER.

The market operator will apply a pre-determined suspension pricing schedule for each NEM region. A compensation regime applies for eligible generators who bid into the market during suspension price periods.

In making the announcement AEMO CEO, Daniel Westerman, said the market operator was forced to direct five gigawatts of generation through direct interventions yesterday, and it was no longer possible to reliably operate the spot market or the power system this way.

“In the current situation suspending the market is the best way to ensure a reliable supply of electricity for Australian homes and businesses,” he said.

“The situation in recent days has posed challenges to the entire energy industry, and suspending the market would simplify operations during the significant outages across the energy supply chain.”

Edge wish to reiterate, this is not a physical supply issue. AEMO directed 5GWhs of physical generation into the market. If generators can operate when under direction, they do not have a physical reason to not generate (such as maintenance, overhaul etc), so the reduced availability we are seeing has to be a commercial trading decision to either price volume into higher price bands or to remove availability in the maximum availability bands of their bids. The availability is there, the generators are just not offering it via the spot market.

The market suspension is temporary, and will be reviewed daily for each NEM region. When conditions change, and AEMO is able to resume operating the market under normal rules, it will do so as soon as practical.

Mr Westerman said price caps coupled with significant unplanned outages and supply chain challenges for coal and gas, were leading to generators removing capacity from the market.

He said this was understandable, but with the high number of units that were out of service and the early onset of winter, the reliance on directions has made it impossible to continue normal operation.

The current energy challenge in eastern Australia is the result of several factors – across the interconnected gas and electricity markets. In recent weeks in the electricity market, we have seen:

  • A large number of generation units out of action for planned maintenance – a typical situation in the shoulder seasons.
  • Planned transmission outages.
  • Periods of low wind and solar output.
  • Around 3000 MW of coal fired generation out of action through unplanned events.
  • An early onset of winter – increasing demand for both electricity and gas.

“We are confident today’s actions will deliver the best outcomes for Australian consumers, and as we return to normal conditions, the market based system will once again deliver value to homes and businesses,” he said.

What does it mean for generators and end users.

  • Bidding and dispatch will continue as usual under the market rules.
  • Dispatch instructions will be issued electronically via the automatic generation control system as usual
  • If required AEMO may issue dispatch instructions in any other form that is practical in the circumstances.
  • Spot prices and FCAS prices in a suspended region continue to be set in accordance with NEM rules or under the Market Suspension Pricing Schedule.

The Market Suspension Pricing Schedule is published weekly by AEMO and contains prices 14 days ahead.

The market will continue to operate under the Market Suspension Pricing Schedule until the Market operator determines the market is able to return to normal conditions and the suspension is revoked.

Drivers behind potential load shedding

In the energy market, probably not unlike most complex markets / industries, we never let the truth stand in the way of a good mainstream news story. So much so, at Edge we struggle to watch mainstream news!

Yesterday Edge highlighted that a tight supply balance was not the key driver for the unprecedented high prices occurring in the spot and contract markets.

As previously outlined, generators bidding behaviour is playing a pivotal role, lifting the average price in the spot market as their spot traders shift volume into higher price bands. This pushed spot prices so high that on Sunday the market reached the cumulative price threshold (CPT). This means that the sum of spot prices in a seven-day period hit a level which caused AEMO to intervene and cap prices until the market returns below this threshold.

As has been widely discussed on Sunday evening, AEMO stepped in and controlled the spot price once the sum of the previous 2,016 (7 days) trading intervals equalled the cumulative total of $1,359,000. The cumulative CPT is equivalent to an average price of $674.16/MWh for the seven-day period.

During market intervention, spot prices in the relevant region are capped at $300/MWh.  This commenced at 6.55pm on Sunday night in Queensland and will continue until the 7-day average drops below the CPT. Once this is achieved the CPT remains on foot until at least 04:00 the next trading day.

Since Queensland hit the cap on Sunday, we have now seen every mainland region in the National Electricity Market (NEM) also hit the CPT. As at publication, intervention pricing is currently enacted in all of these regions (QLD, NSW, VIC, and SA). Tasmania is currently under threat also.

During market intervention the maximum spot price can only reach $300/MWh (there is also a floor of -$300/MWh). $300/MWh is currently lower than the short run marginal cost (SRMC) of many gas generators when priced against the current gas price, which is also currently capped by AEMO (at $40/GJ).

A consequence of capping these markets is higher priced generation withdraws from the electricity market, as an example gas generator have a Short Run Marginal Cost (SRMC) of generation of roughly $400/MWh based on a fuel cost of $40/GJ, but with a cap of $300/MWh on the electricity generated it results in generators removing their availability from the market which in turn results in regional availability dropping. Hence subsequent threats of power outages and the potential requirement for load shedding.  It’s a case of the market being more under threat from commercial drivers than physical drivers.

The commercial dynamics of the current market create a perceived lack of availability in the market and leads to generators looking to other (non-capped) revenue streams for their generation stack. This is precisely what occurred over Monday with 607MW of availability being removed from QLD available generation, and 930MW removed from NSW. The drop in dispatchable generation resulted in AEMO publishing a Lack of Reserve (LOR) forecast and requests by AEMO for a market response. Rather than this call being answered, generators held firm and did not place generation back into the traditional bid stacks.  Across Monday the LOR dropped further as more generation disappeared into the ancillary market and as we approached the evening peak AEMO called an LOR3, which resulted in AEMO also calling on Reliability and Emergency Reserve Trader (RERT) providers to fill the availability gap.

Overnight AEMO’s action on calling RERT prevented load shedding, however this may not be the case in NSW tonight where 590MW of load is forecast to be interrupted at 19:00. If there is insufficient support under RERT to compensate for this supply shortage, we could see load shedding.

With all mainland NEM regions currently operating under the CPT we expect to see more market intervention, and those generators exposed to a capped gas price removing volume out of the market as electricity prices are capped at levels below their SRMC. This is likely to see AEMO needing to intervene in other regions, invoking RERT to source additional availability, or failing that load shedding.

High electricity prices – What’s really driving them?

Written by Alex Driscoll, Senior Manager – Markets, Trading, and Advisory

In recent weeks we have seen a rapid increase in the cost of electricity both in Queensland (“QLD”) and New South Wales (“NSW”).

The chart shows how spot prices (light blue line) and forward prices in QLD have increased considerably since mid-2021. Most notably, we’ve seen frightening increases since mid May 2022.

The question is, what is really driving these unprecedented high prices?

Underlying fuel costs are playing their role, as we’ve seen significant increases in the cost of gas and coal resulting from the Ukraine crisis. Recent weather conditions on the east coast of Australia have also adversely impacted coal deliveries.

Analysis of the supply / demand balance and the bidding behaviour of participants is also in focus. Whilst underlying fuel prices have had a part to play, trading behaviour appears to be playing a leading role in the most recent electricity price increases. At a high level, the structure of the bid stack is a key driver to volatility occurring in QLD and NSW over the past few weeks.

Having analysed the market Edge2020 have found that small changes in the supply / demand balance coupled with strategic bidding behaviour has had a significant impact on spot prices.  Edge2020’s analysis shows that as solar generation diminishes the market power and influence on the spot price shifts from intermittent generation such as solar, to thermal generators such as gas-fired and coal fired generation.  With surplus availability of generation across the states, high demand or scarcity of supply are not the key drivers for the higher prices.

Both QLD and NSW bid stacks reflect the recent strategic bidding of generators in these regions. The bid stacks show how peaking plant are dispatching units at elevated prices, well above levels supported by inflated gas prices. Bid stacks also indicate that coal fired generation is not operating at full capacity. In the absence of news to the contrary, we can assume that output has been restricted for commercial reasons rather than technical limitations. Noting that no re-bids with technical limitations were published during the period analysed.

As spot market volatility has increased, as to have prices across the forward market, with uncertainty and risk having been priced in significantly. Views on future fundamentals remain broad, resulting in differing strategies between forward traders. Whilst spot traders successfully maintain unprecedented volatility in spot prices however, it’s difficult for forward traders to sell into this market. Once the opportunity presents to do so, we could see significant spreads and chunky declines in forward pricing.

 

 

Renewables – cheapest generation in Australia

On Friday, CSIRO released a draft of its latest annual GenCost report. The report is used by AEMO for some of its inputs and assumptions in their publications such as the ISP and the ESOO. The report calculates the expected levelised cost of electricity (LCOE) from a range of generation technologies.

In this year’s report, wind and solar continue to be Australia’s cheapest generation technologies. The report also explores the impact of storage on wind and solar, with the addition of batteries, wind and solar still outperform coal and gas.

The 2021-22 GenCost report estimates solar has a levelled cost of between $44 to $65/MWh and wind costs range between $45 to $57/MWh. The large range in costs is a direct relationship between the scale of the projects.

The CSIRO estimate to build a new baseload coal-fired power station would result in a LCOE of up to $118/MWh and gas is not far behind at $111/MWh. For units with a lower utilisation rate compared to a baseload unit, the LCOE would be significantly higher.

The report also looked into the future and predicts how the cost of generation technologies will change. It is likely the cost of coal and gas technologies will remain constants, in my view they will increase as equipment costs increase, access to specialist skilled labour decreases and capacity factors drop. On the other hand, the CSIRO predicts solar, wind, batteries etc will continue to drop in price resulting in lower LCOE into the future.

With a rapidly changing energy landscape, the CSIRO have also looked at the cost of integrating intermittent generation with storage and grid support services. The CSIRO predicts the integration of technologies and services will add as little as $10/MWh to the LCOE of the generation asset alone. Even with this integration, renewable as considerably cheaper than coal or gas-fired generation.

The study also found if Australia goes down the “gas led” recovery it is highly dependent on the cost of gas. There is a slim chance that gas can compete with renewables but only if gas prices are below $6/GJ and the gas-fired generator has a capacity factor of 80% or above.

If any of the existing coal-fired generators go down the track of installing Carbon Capture and Storage (CCS) it will make them less competitive leading to lower capacity factors. CCS is predicted to increase the LCOE of between $162 and $216/MWh. If the technology is used on Gas fired assets it is likely to increase the LCOE to between $107 and $170MWh.

Stepping outside conventional technologies, the CSIRO would envisage if Australia went down the nuclear path it would result in the highest LCOE of any generation technology.

With the move to a hydrogen economy, the CSIRO have also included the cost of electrolysers, while expensive now the expectation is that they will drop in price by 75% over the next 10 years and by up to 90% by 2050.

Although the GenCost report is currently out for stakeholder consultation it is an interesting view into the future of the Australian energy market.

Federal Government King Review

Recently the Australian Government released findings of the King Review, accepting 21 of 26 recommendations to incentivise greenhouse gas (GHG) emissions abatement from industry.

The focus of the Expert Panel review was the development of rules to credit emissions reductions below Safeguard Mechanism baselines. Credits created under the proposed mechanism could be used to meet compliance obligations under the Safeguard Mechanism.

The panel recommended producing new credits generated under the scheme, known as Safeguard Mechanism Credits (SMCs). The SMCs would be different to the Australian Carbon Credit Unit (ACCU) offsets. SMCs would be for transformative abatement projects based on changes in emissions intensity rather than absolute emissions.

The proposed crediting mechanism would be similar to a baseline and credit framework scheme employed under current legislation however the baseline component of the framework does not account for absolute emission increases. The proposed mechanism will separate an emissions intensity crediting baseline that is focused on ‘transformative’ projects. The new credits will have lower environmental integrity due to the lower threshold for creation of credits for potential abatement projects. The creation of these credits will result in a two speed carbon price.

The Review observations that SMCs could be purchased at a price set by the market or at a fixed price. The price may also be linked to the existing ACCU price. As a result, lower quality SMCs would be expected to trade at a discount to ACCUs.

The Review saw the potential for LGCs to increasingly be considered for use in carbon markets due to their implicit carbon abatement value. It is not proposed to link LGCs in the new scheme.
